I see, a VMware feature, thanks for clarifying. I suppose it's a nice idea in theory, but you'd have to be crazy to use that in production, or for any workload

I see, a VMware feature, thanks for clarifying. I suppose it's a nice idea in theory, but you'd have to be crazy to use that in production, or for any workload that you care about. It would just be a ticking time bomb.
- tremon 6y agoHyper-V can do that too, and so can you under Linux. It's called thinly-allocated disks, sparse files, or the dm-thin device mapper target. Professional SANs also allow you to overallocate the total size of the iSCSI volumes offered. Yes, I've seen that time bomb go off on multiple occasions. Never on my watch though.
